Clean Cities Strategies

 § Replace petroleum with alternative and
   renewable fuels


 § Reduce petroleum use through fuel


   efficiency measures, smarter driving

   practices, and idle reduction

 § Eliminate petroleum use by promoting
   mass transit, trip elimination, and
   congestion mitigation                           Eliminate

 Clean Cities has saved more than 4.5
 billion gallons of petroleum since 1993.

Basics: What Is Idling?

Idling is running a vehicle engine while the vehicle
isn’t moving. Vehicle operators idle for a number of
reasons—some better than others.

Clean Cities / ‹#›
Basics: What Kinds of Vehicles Idle?

Light duty
• Passenger vehicles, including taxis,
   police cruisers, and some light

Medium duty
• Utility vehicles, delivery trucks,
  shuttle buses, ambulances

Heavy duty
• Long-haul trucks, tour buses,
  school buses
                                         All vehicle types may idle, but not necessarily
                                         for the same reasons.

Basics: Why Do Drivers Idle?

• Habit
• Power
       – For onboard auxiliaries
         (e.g., lights, computers)
       – For work trucks (power
         take-off, or PTO)
       – For moving in creep

Basics: Idling for Power

Power for Auxiliaries

• For driver and passenger safety
  and comfort
• To provide power for warning lights
  and communications equipment
• To maintain proper temperature for
  sensitive equipment and goods

Clean Cities / ‹#›
Basics: Idling for Power, cont.

Power Take-Off (PTO)

•   Power take-off refers to a
    device that diverts power from
    a vehicle engine to power
    another device (e.g., hydraulic
    lift on a bucket truck).

•   PTO powers nonpropulsion
    functions on work trucks.

Other Workday Idling

•    “Creeping” in line

•    Some cases of waiting to load or
     unload goods or passengers,
      •     Delivery trucks
      •     Transit buses and motor
      •     Shuttle buses
      •     Taxis

Clean Cities / ‹#›
Basics: What’s Wrong with Idling?

• The cost of fuel (for which the vehicle owner
  gets 0 mpg)
      •    Idling wastes about 6 billion gallons of fuel per year; about half of that is
           from trucks idling overnight and during the workday

• Increased petroleum consumption and reliance
  on nonrenewable resources

• Engine wear
      •    Increased maintenance costs

Basics: What’s Wrong with Idling? cont.

• Air pollution
      • Harmful emissions,
        including greenhouse
        gases and those that
        cause smog
      • Potentially costly
        regulatory consequences

• Noise

• Idling is illegal in
  some states and

Basics: Petroleum Use and Emissions

• In the U.S., idling consumes about 4% of oil imports and about 8% of
  truck fuel.
• More than 1 million long-haul trucks operate on U.S. roads, with nearly
  ¾ of these idling their engines overnight.
• Half of idling fuel losses are estimated to be from everyday
  (noncommercial) drivers.

Benefits: Idle Reduction Is the
Low-Hanging Fruit of Fuel Economy

                                    Idle-reduction equipment
                                    pays for itself in 6 months to
                                    2 years (at 2013 fuel prices).

                                    payback time for a long-haul
                                    truck that idles an average of
                                    40 hours per week.

A Weighty Issue

Some idling solutions can
add a lot of weight to a
vehicle. Some, but not all,
states provide a weight
exemption for these devices.

    Availability: Options for Heavy-Duty
    Vehicles, cont.
Off-board Options
•     Single system
        – Hookup, via a window adaptor,
          provides heating, cooling,
          electrical outlets, and amenities
          such as TV (no on-board
          equipment required)
•     Dual system (shore power)
        – Power connection allows driver
          to plug in to power on-board
          equipment, such as heater, A/C,
          computer, and appliances such
          as microwaves

Light-Duty Vehicles

Driver Education, Policy Implementation, Schedule Adjustments
• Vehicle/fleet telematics (to monitor driver behavior, including idling time) can
  support education and policy.

Devices and Technologies
• Idle limiters (engine shutdown timers)
• Automatic engine stop-start controls with battery-charge monitor
• Air and coolant heaters
      • Air heaters operate with a flame and blower
      • Coolant heaters circulate warmed coolant from the engine to the cabin; can
        provide heat for several hours
• Small fans (blow heat out of a hot vehicle)

                                                                     Photo courtesy of Energy Xtreme.
